3 claims.

'Ihis invention relates to window screen ccnstructionv or the like, and particularly to fastening means therefor.

"One object of the present invention is to pro- 53 vide novel means for securing screenV frames,

storm windows or the like, to a window lcasing in such manner that the frames may be handled, and the fastening means manipulated from the inner side of the casing.

Another object of the invention is to provide novel means whereby a plurality of screen frames, for example, may 'be separately positioned in a window casingand maintained in substantially vertical alignment, and wherein the fastening means are such that by securing the last positioned frame in place, both frames are secured against accidental or unauthorized displacement with respect to each other and to casing.

A further object'of the invention is to provide a novel, simple, economical and eiiicient arrangement of screen frames and fastening means therefor. v

A still further object of the invention is to improve devices of the character described in sundry details hereinafter referred to and particularly pointed out in the appended claims.

One embodiment of the present invention as applied to window screens is shown for illustrative purposes in the accompanying drawing, in which:

Fig. 1 is an elevational outside face view of a window and screen structure embodying features of the present invention;

Fig. 2 is an enlarged sectional elevational view of the structure illustrated in Fig. 1 and taken substantially as indicated by the line 2--2 thereof;

Fig. 3 is a further enlarged fragmentary perspective view of a portion of the window casing and screen construction illustrating the manner of securing the lower portion thereof to the window casing; and

Fig. 4 is an enlarged fragmentary sectional elevational view of the upper fastening means taken substantially as indicated by the line 4--4 of Fig. l.

In the illustrative embodiment, the present invention is shown in conjunction with a window casing of ordinary construction indicated, as a whole, by the numeral 5 and comprising a sill t, top 1, inner stops 8 and outer side and upper stopsrS and II, respectively, said casing having upper and lower window sashes I2 and I3, respectively, slidably mounted between the respective stops.

the Window As'illustrated in the drawing, the present invention comprises a pair of upper and lower screenframes indicated, as a whole, and respectively, by the numerals I4 and I5, each comprising upper and lower rails I6 and Il, respec- 5 tively, and side rails I8, to which are secured a screen fabric I9 of the respective screen frames.

For securing the lower screen frame I5 to the window ycasing and snugly against the outerstop 9 thereof, a pair of hook-like'members 2| shown,v l0' in the present instance, asof L-shape construction, are mounted on the. respective side rails I8 ofthe lower'screen frame and adapted to engage, respectively,l a pair of studs shown, inthe pres- L ent instance,` as screws 22 mounted in the outer if stopsQ, as clearly illustrated in Figs. 2 and 3.

As clearly shown in Fig. 2, the top rail I 6 of the lower screen frame I5 and the bottom rail I'I of the upper screen frame E4 are recessed or rabbeted as indicated at 23 and 24, respectively, .20 (Fig 2)' to provide overlapping portions at the adjacent ends vof the respective frames and which enter the recess or rabbet of the opposite frame, the projection on the upper rail IS ofv the `lower frame I5 being at the outer'side thereof 25 and cooperating-with the outer stop 9 in a manner to retain the screen frames I4 and I5 in substantially vertical alignment and to secure the lower rail I'I of the frame i4 against outward movement with respect to the window casing, 30 while at the same time permitting the upper end of the upper frame I4'to be swung outwardly.

For securing the upper end of the screen frame I4 within the window frame and against the outer stops 9 and II, the rail I 6 of the frame I4 is `35 provided with fastening means shown, in the present instance, as a plunger or bolt 25 slidably mounted in a sleeve 26 carried by the rail I6, and having a spring 2l operatively related to the bolt and sleeve in a manner to normally urge the bolt 25 in an upwardly direction therefrom and into a recess 23 formed in the top I of the window casing 5, as clearly illustrated in Figs. 2 and 4, the bolt 25 having an elongated stem 29 extending downwardly therefrom through the lower end portion of the sleeve 26 and provided at its outer end with a finger piece or ring 3| by which the bolt may be manually operated to withdraw the bolt fromthe recess 28 when it is desired to remove the screen frame I4 from the casing.

It will be observed from the foregoing description that the present invention provides a novel construction and arrangement for securing the lower screen frame I5 in operative position with respect to the casing 5 and stops 9, and by reason 55 of the rabbets and projections on the adjacent portions of the respective screen frames, the lower portion of the upper frame I4 may be secured in operative relation to the window casing and stops 9. Also that when the bolt is positioned in the recess 28, the entire structure is secured in operative position with respect to the window casing, and the screen frames secured in substantially vertical alignment and locked in place with respect to the casing.

It will be noted that the securing means are mounted on the inner side of the screen structure to facilitate mounting of the screens from the inner side of the casing, and to protect the securing means soY far as possible from unauthorized operation or tampering from outside the screen construction.

Obviously, the present invention is not limited to the precise construction and arrangement shown and described as the same may be variously modiiied. Moreover, all the features of the invention need not be used cojointly as the same may be used to advantage in variously different combinations and subcombinations.

What I claim as new and desire to secure by Letters Patent is:

1. In a window screen, the combination with a.v

window casing having a recess therein and outer stops associated therewith, of upper and lowerV screen frames positioned within said casing and in substantially vertical alignment, said frames having overlapping cooperating portions on their respective adjacent ends and cooperable with said outer stops for maintaining said frames in such alignment, cooperating means mounted rigidly on said lower frame and said stops, respectively,

for securing the lower frame snugly against the stops and within said casing, and a spring actuated manually operated fastening member slidably mounted in said upper frame and engage.- able with said recess for securing the upper frame in operative position with relation to said stops and within the window casing.

2. In a window screen, the combination with a window casing having a recess therein and outer stops associated therewith, of upper and lower screen frames positioned within said casing and comprising top, bottom and side rails, the top rail of the lower frame and the bottom rail of the upper frame being rabbeted to provide overlapping projections on the respective frames adapted to enter the rabbet of the other frame, the projecting portion on the lower frame being at the outside o-f the projection on the upper frame, cooperative means mounted rigidly on the side rails of the lower frame and said stops and within said casing, respectively, for securing said lower frame snugly against the stops, and a manually operated bolt mounted in said upper frame and engageable with the recess formed in said casing for seeming said upper frame in operative position with relation to said stops and within the casing in a manner to secure said lower frame against vertical movement with respect to said casing.

3. In a window screen, the combination with a window casing having a recess therein and outer stops associated therewith, of upper and lower screen frames positioned within said casing and comprising top, bottom and side rails, the top Ythe projecting portion on the upper rail of the lower fra-me being at the outside of the'projec-l tion on the lower rail of the upper frame, a. pair of studs mounted on said stops at the respective sides of the window casing, a pair of hook-like members on the respective side rails of said lower frame and engageable with said studsv for securing the lower frame snugly against said stops and within said casing, and a spring actuated-manually operatedy bolt slidably mounted in the upper rail of said upper framel and engageable with the recess formed in said casing for securing said upper frame in operative position with relation to said stops and within the casing in 'a mannertoY secure said lower frame and hook-like members mounted thereon against vertical movement with respect to said casing and the studs mounted on said stops.
